Maintaining the Descriptive Geometry’s Design Knowledge

One of the most important parts of product lifetime management is maintaining the knowledge thatwas implemented during product design.However, the problem occurs when the design knowledge has been lost or it is left written in the old form. In this work, the design knowledge is presented by the traditional drawing of an object using descriptive geometry. The aim is to present an approach to refresh the drawing with traditional CAD software and preserve the design knowledge.The line segment and the pentagon pyramid were drawnon paper using the traditional drawing technique with a pencil considering descriptive geometry rules. As a part of the traditional drawing method, they were never processed by conventional CAD software. They are imported as an image file, scaled, and processed with the aim to extract the written knowledge for further maintenance in a new CAD form. With such an approach, the design knowledge is refreshed and ready to be used again. This approach can help save time in much more complex applications such as in a redesign or reverse engineering process of products and their life-cycle management overall.
